The Ellenburger Group of the West Texas Permian Basin is part of a Lower Ordovician carbonate platform sequence that covers a large area of the United States. During the Early Ordovician, the Permian Basin area was located on the southwest edge of the Laurentia plate between 20° and 30° latitude. The equator crossed northern Canada, situating Texas in a tropical to subtropical latitude. The are...

Fabrics are typical porous material and can be treated as mixtures of fibers and air. There is no clearly defined boundary and is different from a classical continuum for fabrics. It is complex to proceed with the theoretical analysis of fabric behavior. There are two main reasons (Hearle et al., 1969) for developing the geometrical structures of fabrics. One is to be able to calculate the resi...

Fabric pilling is a serious problem for the apparel industry, causing an unsightly appearance and premature wear. Woolen products are particularly prone to pilling. Recently, a process for production of woolen nonwoven apparel fabrics has been commercialized in Australia, and may lead to new markets for Australian wool. However, the success of such nonwoven fabrics will partly rely on their pro...

ZnO nanoparticle-based multilayer nanocomposite films were fabricated on cationized woven cotton fabrics via layer-by-layer molecular self-assembly technique. For cationic surface charge, cotton fabrics were pretreated with 2,3-epoxypropyltrimethylammonium chloride (EP3MAC) by pad-batch method. XPS and SEM were used to examine the deposited nano-ZnO multilayer films on the cotton fabrics. The n...

In this study, the influence of dyeing on the antibacterial efficiency of polyamide and polyester fabrics loaded with colloidal Ag nanoparticles and the influence of the presence of Ag nanoparticles on the color change of dyed fabrics were investigated. Dyes C.I. acid green 25 and C.I. disperse blue 3 were used for dyeing of polyamide fabrics, while dye C.I. disperse violet 8 was used for dyein...

Geological analysis of planets typically begins with the construction of a geologic map of the planets' surfaces using remote data sets. Geologic maps provide the basis for interpretations of geologic histories, which in turn provide critical relations for understanding the range of processes that contributed to the evolution. Because geologic mapping should ultimately lead to the discovery of ...

deteriorated urban textures are areas of a city isolated from developmental life cycle. they have turned into the focus of problems and inefficiencies. the evaluation of renewal actions claims to promote residents’ satisfaction in some cases. at the same time of improving objective and economic quality of life, there are claims regarding the lack of any improvements in their subjective quality ...
